The geology of the oceanographer fracture zone: A model for fracture zones
Journal of Geophysical Research, 1976An unreversed refraction experiment located 325 km west of the center of the Oceanographer transform and aligned along the axis of the fracture zone yielded information on the velocity structure of the crust within the fracture zone axis. A layer 2 km thick having a compressional wave velocity of 4.4 km/s overlies a layer with a compressional wave ...

Geology and Geometry: A Review of Factors Affecting the Effectiveness of Hydraulic Fracturing
Proceedings of SPE Eastern Regional Meeting, 2005Abstract Thousands of wells are hydraulically fractured in the Appalachian Basin each year with little clear understanding of what the resulting fracture actually looks like. A number of variables exist in the subsurface including natural fractures, permeability variations, in-situ stresses, faults, etc.

Folding and Fracturing of Rocks : the birth of modern structural geology
Geological Society, London, Special Publications, 2018Abstract In 1967, the publication of John Ramsay's book, Folding and Fracturing of Rocks , was a landmark event that affected both of us, inspiring us into careers in structural geology. At that time, one of us was a postgraduate student at Imperial College, London, the other a second-year undergraduate at

Description of Natural Fracture Systems for Quantitative Use in Petroleum Geology (1)
AAPG Bulletin, 1990We present a method for estimating fracture porosity and permeability from measurements of fractures in small samples of a fracture system. A fracture system is divided into domains from which samples are collected. Lengths, widths, and numbers of fractures present in samples are measured and then summarized in density and distribution functions. These

A modified seismic reflection approach for engineering geology investigation in fractured rock zones
Engineering Geology, 2020Abstract Delineating soil/rock interface is critical for geotechnical and tunnel site investigations in engineering geology. In Singapore, we also need to draw attention to local faults and fractured rock zones because the regional geology of Peninsular Malaysia and Singapore contains some minor, steep and brittle faults propagating at some areas in ...
